Hello everyone,

I am currently working with Elasticsearch server version **9.2.0**.  
I would like to retrieve vector fields in search responses by specifying:

```auto
"_source": {
  "exclude_vectors": false
}

```

However, when using the **Elasticsearch Java Client** (`elasticsearch-java`), I cannot find a way to set this option in `SearchRequest.Builder` or `SourceConfig`.

Currently, I can only control `_source` at a general field level using `includes` or `excludes`, but I need a way to explicitly **rehydrate vector fields** in the search results.

Could you please advise if there is a supported way to achieve this in the Java Client, or if this is a missing feature?

What does the mappings for the index look like?
